The 18sqm house — about a 10th the size of the average SA home — is made of timber and corrugated iron fixed onto a steel frame, supported by a trailer.

Mitchell — who had little prior building experience aside from woodwork classes at school — has learnt to install windows, roofing and cladding, lay flooring, while project managing the build on a $30,000 budget.

The property’s exterior is complete and he expects to have the interior completed by October.

“Once I sort of got exposed to the idea of it and the whole concept of it I was really hooked on it, it seems really cool to be able to build your own home, it’s a bit more affordable for especially younger people like myself,” he said.

“They (friends) always say you’ve picked a pretty crazy project for Year 12, it’s pretty cool to see other people’s reactions to what I’ve done.”

He initially intends to rent it out as an Airbnb but eventually use it as his first step onto the homeownership ladder and avoid the rental market.
